Because of its more efficient propellant, this round is expected to be a more powerful, longer-range rocket. Except for the propellant, it is of conventional Army design.
Seven cylindrical powder sticks, 18.5 inches long and 1.85 inches in diameter, furnish the power. The grid type of support is used instead of the conventional trap, and the igniter is housed against the motor wall, instead of being placed in the center. Safe temperature limits for this round are from -20º F. to +120º F.
No information about functioning.
No information about hazardous components.
Nothing else to see.
